Ballscrews consist of a screw spindle and a nut integrated with rolling elements that cycle through a return mechanism. Ballscrews convert rotary motion into linear motion, and are most commonly used in industrial machinery and precision machines. Hiwin Corporation provides a wide range of ballscrew configurations to satisfy your special application requirements. Hiwin has the capability of producing JIS C0 class ground ballscrews, and DIN 5 class (up to 23 microns) for precision rolled ballscrews. Ballscrew O.D. ranging from 4mm to 120mm, and with Dm-N values up to 220,000.

The Ball Screw is a high-efficiency method of converting rotary motion to linear motion by using a recirculating ball mechanism between the screw shaft and the nut. Compared with a conventional sliding screw, the ball screw requires driving torque of one-third or less, 

PMI GROUPwas established in 1990. It''s highly involved in manufacturing of ballscrews, precision ball screw spline, linear guideway, ball spline and actuator, which is the critical component of precision machinery and mainly applied to Machine Tool, Electric Discharging Machine, Cutting Wire Machine, Plastics Injection Machine, Semi-conductor Equipment, Precision Orientation Equipment and other equipments and machines.

The ball screw drive is an assembly that converts rotary motion to linear motion (or vice versa).  It consists of a ball screw and a ball nut packaged as an assembly with recirculating ball bearings.  The interface between the ball screw and the nut is made by ball bearings which roll in matching ball forms.  With rolling elements, the ballscrew drive has a very low friction coefficient and is typically greater than 90% efficient. The forces transmitted are distributed over a large number of ball bearings, giving a low relative load per ball comparatively.
